WASHER-MAKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 679,699, dated July 30,1901.

Application filed geptemher 291 1900- Serial No- 3l 559. (No model.)

To all whom, (It may concern.-

Be it known that I, J osnrn MMAsoN, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inMachines for Making lVashers, of which the following is a specification.

My invention relates to improvements in machines for making washers atone operation by the simultaneous action of the dies and piercing-punch;and the objects of my invention are, first, to provide a machine whichshall be more simple and efficient in its mechanism than any machineheretofore in use, and, sec- 0nd, to so construct the machine as toenable several washers to be simultaneously punched from the same sheetof metal without unduly complicating the mechanism, thus greatlyreducing the cost of the labor employed in the manufacture of thewashers. I attain these objects by the mechanism illustrated in theaccompanying drawings, in which- Figure 1 is the side elevation of amachine embodying the main features of my invention. Fig. 2 is asectional view on the line 2 2 of Fig. 1, showing the cam for operatingthe stripping-plate for stripping the sheet metal from the lower diesafter the Washer has punched. Fig. 3 is a sectional view on the line 3 3of Fig. 1. Fig. -:t is a top or plan view of the-machine. Fig. 5 is asectional View on the line 5 5 of Fig. 1, showing the arrangement of thelower dies and the stripping-plate in plan. Fig. 6 is a front elevationof the upper portion of the machine, showing more fully the meansemployed to operate the carrier-plate for removing the washers from theupper dies as they are discharged therefrom. Fig. 7 is a view of aportion of the vertical spindle which operates the carrier-plate,showing the helical groove, the purpose of which will hereinafter bemore fully described. Fig. 8 is an underneath plan view of the upperdies and their accompanying parts. Fig. 9 is a transverse sectional viewof the upper die.

Similar letters of reference refer to similar parts throughout theseveral views.

A represents the frame of the machine of the usual configuration ofpress-machines.

B is the driving-shaft, provided with the usual fly-wheel Z) and pinionZ), which gears with the gear-wheel c on the main shaft 0 of themachine.

The ram or head 61 is adapted to be vertically reciprooated in the upperprojection a of the frame by means of the eccentric c on the front endof the shaft 0 in the well-known manner. A bed-platef rests upon thelower projection a of the frame. The wedge-shaped slides usuallyemployed to give the bed-plate a vertical adjustment are dispensed with,and when it is necessary to raise the bedplate blocks (not shown) can beplaced between the bed-platefand the lower projection a of the frame.The bed-platefcontains a series of dies g, arranged, preferably, in astraight line and adapted, in conjunction with the upper die H, to formthe outside edges of the washers. The upper die H is preferably formedof one piece and secured to the lower side of the sliding head d, asillustrated in Fig. 3 of the drawings. Centrally arranged in each of theopenings 7b in the upper die II is a punch h, which, in conjunction withthe opening in the lower dies g, form the holes of the washers.Surrounding the punches 71 are sleeves 7L2, which fit the openings h inthe upper die and are provided at their upper ends with enlargedportions to retain said sleeves in the upper die, all of which issubstantially old. These sleeves are also provided with the usual pins hto prevent the washer when ejected from adhering to the sleeve W. Ahorizontal bar '5 is provided for knocking out the washers from theupper die H. It is situated in a slot i, extending through the frame andhead d, as shown in Figs. 1 and 3. The bar i is restricted in its upwardmovement by the set-screws i and rests upon the verticallymovable pinsj, which in turn rest upon a bar or plate k, which is seated upon theenlarged ends of the sleeves 71. Heretofore in machines for punchingwashers singly the pins jhave rested directly upon the sleeves 72. butby interposing the plate or bar is as many may be punched at the sametime as may be found convenient without necessarily complicating themachine.

A carrier-platel is provided for carrying the Washers after they areejected from the upper dies to the side of the machine, said carrierplate being attached to a vertical spindle Z by means of a bracket P.The spindle Z has a helical groove Z which is engaged by a set-screw Zin the nut Z said nut being connected with the movable head 61 by meansof a strap Z and adapted when the head d is reciprocated to cause thespindle to be rotated a quarter-revolution, thereby bringing thecarrier-plate under the dies when the washers are ejected therefrom andremoving the same to the side of the machine, where they are knocked offthe carrier-plate by a tripper 'm in the usual manner, as shown in Fig.3.

A stripper-plate n strips the sheet metal out of which the washers arepunched from the lower dies 9 after the upper die H is withdrawn. Thisstripper-plate is supported by rods n, having at their lower ends yokesn which rest upon the front ends of levers n pivoted at W, said leversbeing connected at their rear ends by connecting-rods n to a yoke n. Theyoke n is located in an opening a in the frame of the machine,immediately beneath and adapted to be operated by a cam 0 mounted on themain shaft 0. The cam 0 when the head (1 is in its raised positionforces the yoke 11 and con meeting-rods ,downward, thereby causing thelevers n to raise the stripper-plate and strip the sheet metal out ofwhich the washers hax e been punched from the lower dies g. The momentumof the plate operating the stripper-plate might cause the same to belifted higher than necessary, and to control this a bolt 71 is screwedinto the lower part of the frame and serves to limit the range ofmovement of the levers n as illustrated in Fig. 1.

Havingthus described the nature of my invention, what I claim, anddesire to secure by Letters Patent, is

1. In a machine of the character described, the combination of a seriesof upper and lower dies and punches, sleeves adapted to force out thecompleted washers, a plate resting on said sleeves, pins resting on saidplate, a bar resting on said pins and set-screws adapted to restrict theupward movement of said bar, all substantially and for the purposes asset forth.

2. In a machine of the character described the combination of thecarrier-plate, a spindie to which said carrier-plate is attached, ahelical groove in said spindle and means attached to the oscillatinghead of the machine for engaging said groove and causing the spindle tobe rotated a portion of a revolution substantially as and for thepurpose set forth.

3. In a machine of the character described, the combination of thecarrier-plate, a spindle to which said carrier-plate is attached, ahelical groove in said spindle, a nut provided with a setscrew adaptedto engage said groove and a strap connecting said nut to the oscillatinghead of the machine substantially as and for. the purposes set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

JOSEPH M. MASON.
